Which radars cover Seneca?
The closest NEXRAD Doppler radar is KARX (La Crosse, WI), about 40 miles north-northwest. Radar beams climb as they travel, so the height of the lowest scan over town decides how low in a storm the radar can see.
| Radar | Distance | Lowest beam over Seneca | View |
|---|---|---|---|
| KARX La Crosse, WI | 40 mi north-northwest | 2,700 ft | Excellent — the lowest scan sees close to the ground |
| KDVN Quad Cities, IA | 116 mi south | 12,100 ft | Limited — the beam overshoots the lowest part of storms |
| KMKX Milwaukee/Sullivan, WI | 123 mi east | 13,200 ft | Limited — the beam overshoots the lowest part of storms |
Beam height is the center of the 0.5° scan above the radar, with standard refraction. Mountains near a radar can block it further.
